Multiple Errors when requiring files
I am trying to use requirejs-rails in my rails project and I am running into problems with it. I have added the gem and ran bundle install, but I am unable to actually require a file. My relevant files are:
application.js
// = require require
require(['jquery'], function($) {
'use strict';
// Your awesome javascript goes here!
// **********************************
// This is just some guff to help you prove that everything works.
// You can and should delete this once everything works.
console.log('Successfully loaded jQuery version: ' + $('body').jquery);
if (typeof $.rails === 'object') {
console.log('The $ object seems to have been decorated by Rails UJS successfully.');
}
else {
console.log('Uh-oh, it seems that $ has not been decorated by Rails UJS. You might want to check this.');
}
// **********************************
});
head of application.html.erb
<head>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= requirejs_include_tag "require" %>
<%= csrf_meta_tags %>
</head>
Then where I am trying to use it:
var antlr4 = require(['foo/antlr4/index']);
var input = 'foobar';
var chars = new antlr4.InputStream(input);
My app/assets/javascripts/foo/antlr4/index.js looks like the following
exports.foo = require('./foo');
exports.bar = require('./bar')
and it gives me ReferenceError: Can't find variable: exports and TypeError: undefined is not a constructor (evaluating 'new antlr4.InputStream(input)')
If I change the head of application.html.erb, to the following:
<head>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'require.js' %>
<%= requirejs_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
It just gives me ReferenceError: Can't find variable: exports. Can anybody help with this issue? I might of included things incorrectly
